8. Valve Restrictors:
The Restrictors Vary in size from Spool to Spool, Some Ports do not use restrictors at all,
See parts page for types and sizes. Restrictors operate by controlling the rate of flow to or
from a Cylinder, This is most commonly done by the size of the Hole the Oil is sent through,
But can be done by Hose Size. There are also 1 way and 2 way restrictors, Check Parts
pages. DO NOT Remove, Change or Modify Restrictors.

Valve Spool Functions & Specs:
In the Chart Cycle Times listed above are close approximations of actual times based on
machine testing, Times indicate the time for the Cylinder to travel the full amount of its extension or
retraction. The lift times up and down are taken with the dipper fully extended and begin with the Deck
flat on the ground. All Cycle times are measured at the rated Tractor RPM. Test Times should be close
to above but can vary some from unit to unit; Times listed are a guide to show approx. what Cycle
times for tour Unit should be.
Valve Leakage:
Maximum internal Valve Leakage from the Cylinder. Ports to Tank at any Valve
Segment, Oil Pressure at 1450 PSI and Oil Viscosity at 102 SSU
